Abstract
An HMD includes a mounting band for surrounding a head H of a user. The mounting band includes a case, a stretching unit, an adjustment mechanism that adjusts a length of the stretching unit to be accommodated in the case by relatively moving the stretching portion with respect to the case, a winding target member, and a spring member which is fixed at a front portion thereof to the stretching unit and at a rear portion thereof wound on the winding target member and in which an unwinding amount from the winding target member changes according to the length of the stretching unit accommodated in the case. The spring member generates elastic force that acts in a direction in which the stretching portion is accommodated into the case. A first elastic force of the spring member generated by a first unwinding amount and a second elastic force of the spring member generated by a second unwinding amount are equal to each other.
